W artykule omówiono zagadnienia oceny ryzyka technicznego związanego z długotrwałą eksploatacją bloków energetycznych. Szczegółowe analizy przeprowadzono dla elementów turbiny parowej. Zdefiniowano źródła ryzyka i konsekwencje uszkodzeń turbiny oraz obliczono prawdopodobieństwo ich uszkodzenia. Podano ilościową ocenę ryzyka w ustalonych warunkach eksploatacji turbiny.

Serious recent failures of power systems revealed the permanent presence of real risk of the loss of the operational continuity of such systems, which may result in hard to predict social and economic effects. Thus, these days more attention is focused on the assessment of the reliability of power systems, which involves both the reliability of energy generation systems and transmission systems as well. The essential factors determining the level of reliability are, among others: the structure of the system, prevailing climactic and atmospheric conditions, level of power reserves, organization of cooperation with related systems, quality of automatic control and safety systems and technical state of power units components. The last factor, concerns, first and foremost, the age of generation units, which is quite advanced in many countries. In the next 10 years over 40% of power stations located in Europe will reach the age of 40 years of operation. This may result in prospective increase of failure frequency of power units and, consequently, reduced reliability of the whole system. In the paper the quantitative assessment of technical risk associated with long-term operation of power units is made. Detailed considerations concern the analysis of the operational risk of steam turbines, which, beside boilers, constitute a fundamental element of a power unit. The sources of risk are presented with possible scenarios of failures. Calculation of the probability of failure are made for random loads and random properties of materials.
